解説
問 45
- ア
正解 In project management, schedule, cost, and quality are competing constraints, and prioritizing one sacrifices one of the others. When you want to shorten the schedule, the standard technique is to add resources such as staff and equipment so that work runs in parallel and is accelerated, thereby shortening the duration — this is called crashing. Option ア reflects exactly this idea: keeping to the schedule by adding resources even while accepting an increase in cost. It shortens the duration without sacrificing quality or scope, so it is the appropriate response.
Incorrectイ
Enhancing the functionality of the system increases the features that must be developed, which actually raises the amount of work. Rather than shortening the schedule, it works to extend it, so it is inappropriate as a response for shortening the duration.
Incorrectウ
Expanding the target scope widens the very range of work to be done, increasing the workload. This runs counter to shortening the schedule, so it is not an appropriate response.
Incorrectエ
Reducing project members decreases the resources that can be deployed, so the time required for the same work actually becomes longer. As a means of shortening the duration it backfires and is inappropriate.
ここがポイント
- The three major project constraints (schedule, cost, and quality — scope is sometimes included) are in competition: prioritizing one sacrifices another. Understand this trade-off relationship.
- Grasp crashing, the representative technique for shortening the duration (adding resources to trade an increase in cost for a shorter duration), together with fast-tracking, which runs work in parallel.
